Hepatocellular carcinoma (HCC) is one of the major causes of morbidity, mortality, and healthcare expenditure in patients with chronic liver disease in India. The Indian National Association for Study of the Liver (INASL) had published its first guidelines on diagnosis and management of HCC (The Puri Recommendations) in 2014, and these guidelines were very well received by the healthcare community involved in diagnosis and management

The aim of this study was to objectively assess swallowing function and factors impacting it after curative intent definitive (chemo)radiotherapy (CRT) for head and neck squamous cell carcinoma (HNSCC). Swallowing function was studied in a cohort of 47 patients with locoregionally advanced (T1-4, N0-3) HNSCC treated with definitive CRT. Objective assessment of swallowing function was done using modified barium swallow (MBS) at baseline (pre-CRT) and subsequent follow-ups. Scoring of MBS was done using penetration-aspiration scale (PAS). Abnormal swallowing was defined in terms of incidence and severity of penetration-aspiration, pharyngeal residue, postural change, and regurgitation. Aspiration, residual, postural change, and regurgitation were present on baseline pre-CRT assessment in 9 (19%), 11 (23%), 10 (21%), and 5 (10%) patients that increased to 11 (29%), 11 (29%), 12 (32%), and 10 (26%) patients, respectively, at 6-month post-CRT evaluation. The proportion of patients with high PAS scores (3-7) increased from 27% at baseline to 37% at 6-month post-CRT evaluation. Among patients (n = 34) with low PAS scores (≤2) at baseline, additional impairment of swallowing function was seen in 53 and 46% at 2- and 6-month assessment, respectively. Residue (44%) and aspiration (18%) domains were impaired in a higher proportion of patients after CRT. Thin and thick barium had higher aspiration and residue function impairment, respectively. Patients with pre-CRT poor subjective swallowing function (P = 0.004), hypopharyngeal primary (P = 0.05), and large tumor volume (P = 0.05) had significantly worse objective swallowing function at baseline as demonstrated by pretreatment PAS scores. This study provides useful information regarding patterns of objective swallowing dysfunction in patients treated with definitive (chemo)radiotherapy. There is significant impairment of objective swallowing function in all domains following CRT, with residue and aspiration domains being affected most significantly.

Background Regimens for palliation in patients with head and neck cancer recommended by the US National Comprehensive Cancer Network (NCCN) have low applicability (less than 1-3%) in low-income and middle-income countries (LMICs) because of their cost. In a previous phase 2 study, patients with head and neck cancer who received metronomic chemotherapy had better outcomes when compared with those who received intravenous cisplatin, which is commonly used as the standard of care in LMICs. We aimed to do a phase 3 study to substantiate these findings. MethodsWe did an open-label, parallel-group, non-inferiority, randomised, phase 3 trial at the Department of Medical Oncology, Tata Memorial Center, Homi Bhabha National Institute, Mumbai, India. We enrolled adult patients (aged 18-70 years) who planned to receive palliative systemic treatment for relapsed, recurrent, or newly diagnosed squamous cell carcinoma of the head and neck, and who had an Eastern Cooperative Oncology Group performance status score of 0-1 and measurable disease, as defined by the Response Evaluation Criteria In Solid Tumors. We randomly assigned (1:1) participants to receive either oral metronomic chemotherapy, consisting of 15 mg/m² methotrexate once per week plus 200 mg celecoxib twice per day until disease progression or until the development of intolerable side-effects, or 75 mg/m² intravenous cisplatin once every 3 weeks for six cycles. Randomisation was done by use of a computer-generated randomisation sequence, with a block size of four, and patients were stratified by primary tumour site and previous cancer-directed treatment. The primary endpoint was median overall survival. Assuming that 6-month overall survival in the intravenous cisplatin group would be 40%, a non-inferiority margin of 13% was defined. Both intention-to-treat and per-protocol analyses were done. All patients who completed at least one cycle of the assigned treatment were included in the safety analysis. This trial is registered with the Clinical Trials Registry-India, CTRI/2015/11/006388, and is completed. Findings Between May 16, 2016, and Jan 17, 2020, 422 patients were randomly assigned: 213 to the oral metronomic chemotherapy group and 209 to the intravenous cisplatin group. All 422 patients were included in the intention-totreat analysis, and 418 patients (211 in the oral metronomic chemotherapy group and 207 in the intravenous cisplatin group) were included in the per-protocol analysis. At a median follow-up of 15•73 months, median overall survival in the intention-to-treat analysis population was 7•5 months (IQR 4•6-12•6) in the oral metronomic chemotherapy group compared with 6•1 months (3•2-9•6) in the intravenous cisplatin group (unadjusted HR for death 0•773 [95% CI 0•615-0•97, p=0•026]). In the per-protocol analysis population, median overall survival was 7•5 months (4•7-12•8) in the oral metronomic chemotherapy group and 6•1 months (3•4-9•6) in the intravenous cisplatin group (unadjusted HR for death 0•775 [95% CI 0•616-0•974, p=0•029]).
